This'ii'ivention has for its object -to provide mechanism for use as an attachment to continuous "feed gointers forl vinvertiirgthe work after it: has passed through the 'jointcrin one `directionto receive a tongue `or groove onione edge and ipresenting it to the-return feed of the machine for travel in the oppoi site' direction to receive a tongue 1 or groove on the other edge.

l0 The-invention vis particularly `designed as anV attachment fou such glue Jointers as yare- The invention `has for itsv object to ac complish the transfer of the Worlr'froin one Work-feed passageway'to the 'otherby means I of 4travelingbelts on Which'it falls Whenrebarsfof tliejointer" and it further has for' its objectto accomplishI the turni-ng of the @Work-f so las -to ibringits icutedge uppermost by causing it to dropoff of Such conveyer -beltsi with its uncut edge loivermost.

Anotheiobjectof the invention is to facilitatey the laction of invert-ing the lWork `by cans-ing it" to engage a downwardly traveling belt in the pathA of its travel on the conveyer beltsl Another object of the invention is to perfect details Iof `construction of sucha return feeder i l Vith the above and other objects inview the invention yconsists in the return feederifor continuous feed jointers as hereiniclaimed and all equivalents Referring to the accompanying drawings,

nation thereof against Whichthefboard .or piece of 'lumber of Whateverlength -vvill bear` as it issues froinsaid Work feed passageway after having @had .i the lirsti matching cutter operation;thereon."Z .This lguider11.6,; as best seenfnin Figlia, is providedwith la narrow fill ledge ll, upon which the work bears as it issues from the jointer. In a vertical cross partition 18 of the frame is a. spring-pressed bolt 19 bearing against a hinged plate 20, which is thereby caused to bear against the inner face of the work and hold it against the guide 1G, but as soon as one piece of worltr passes beyond the edge of the plate 2O by the pressure of the piece of work following it, it is no longer supported at its inner face and consequently, because of the arrowness of the ledge 17, it falls inwardly upon an inclined conveyer belt- 2l. The belt 21 is preferably formed of sheet rubber. with corrugated surface and desirably in a number` of sections as shown and ire-enforced by a stationary back plate 22 so that the work carried upwardly thereby and toward thereturn passageway. rlhis sectional apron passes around a guide roller 23, a driving roller 24h having suitable driving connection from a motor 25 and a tensioning roller 26 adjustable at i2 for maintaining the tension on the apron. At the upper end of the inclined apron there is an oppositeiy inclined guide 2T of a vertical guide wall 28, which is in line with the rear bearing fac-e of the head block l1 of the matcher, while a downwardly traveling conveyer belt 29, also preferably of corrugated sheet rubber and formed in sections as shown, constitutes the rear wall of what is in effect a prolongation of the return feed passageway through the jointer, the bottom or floor of said passageway being formed by a conveyer belt traveling on a flat bearing surface 31 of a bracket frame 44 having vertical adjustment l5 on the main frame. rlhis conveyer belt is suitably driven from the motor 25 and is held tensioned by a belt tight-ener 32. The downwardly traveling apron 29 is mounted on. a bracket frame 33, which is adjustable horizontally by the adjustment d3 so as to adapt it to the adjustments `of the side bar of the jointer according to the thickness of the work being` operated upon and said apron passes around a guide roller 34e on said bracket frame and a driving roller 35 having suitable driving connection with the motor 25 that will permit of the adjustments.

ln operation the work which falls olf of the ledge 17 when released by the springpressed plate 2O drops upon the inclined conveyor 2l and is carried up thereby until its front edge projecting beyond the roller 23 overbalanees it and starts it down the inclined guide 27 against the downwardly traveling apron 29, the speed of which is sutlicient to immediately complete the turn-` ing of the piece of work to bring its uncut edge downwardly into the extension of the return feed passageway, where such edge bears on the cenveyer belt 30 traveling in the direction of the jointer. The werk is speedily conveyed by the belt 30 to the return feed passageway thrrmgh the j oi nter, a guide bracket 36 being provided to bridge the gap between the guide wall afforded by the downwardly traveling apron 2? and the side bar 123 ofthe joinler.

By means of this invention the transfer of the work from one work-feed passageway to the other is accomplished mechanically and expeditiously without danger of jamming the machine. The speed of travel of the belts is such as to remove one piece of werk before another is dropped even when the shortest pieces are used. Should a short piece of work follow a long strip it may find the return feed passageway occupied when il; reaches the top of the inclined conveyer, but it will be held in this position with the apron slij'iping beneath it until the passageway is clear and then, by its engagement with the downwardly traveling apron 2f), will be dropped into said passageway and conveyed to the return feed of the jointer.
